Y Application led August 18, 1898. Serial llo. 688,854. No model.) y

To 'all when@ t may con/cern: Be it known thatI, WALTER SCOTT,'a'citizen of the United States, and a residentuof Plainfield, in thecounty of Union and State of New Jersey, have invented certain new andnsefnllmprovementsin Sheet-Delivery Mechanism, of which the following isa specification.

Thisinvention relates to mechanismV for' delivering sheets ondelivery-boards,and more especially that class of mechanism wherein thesheets are run out dat and then dropped devices hereinafter'more fullydescribed, and

` more particularly pointed out in the claims y elevation in Fig. 8.Y

concluding this specification.

The preferred form of the invention is illustrated in the accompanyingdrawings, forming part of this specification, in which- Figure 1 is aside elevation of part of a machine, showing a sheet-stop, `upper andlower movable grippers, a sheet-support, and operating mechanism for theparts. Fig. 2 is a cross-section of one sideof the frame shown in Fig. 1and showing certain of `the parts shown in Fig. 1 and also part of theoperating mechanism. Fig. 3 is a diagrammatic side view showing theposition of the grippers and sheet-stop at the moment a sheet is run inbetween the grippers. Fig. 4 is a 'like view showing the positions ofthe parts when the grippers close to grip the sheet between them. Fig. 5is a side elevation, partly broken away, to show the working partsbehind of a mechanism embodying the automatic slip-inserting feature ofmy invention. Fig. Gis a plan view of certain features of one form ofmyinvention. Fig. 7 is a detail View of certain features shown in sideFig. 8 isa side elevation, partly broken away to showworking 'partsbehind of a modification of themechanism shown in Fig. 5. Fig. J is aside elevation showing an arrangement of gearing for driving thefeed-cylinder shown in Fig. 8.' Fig. 10 is a cross-section of a pulleyand a shaft, showing a yielding connection between the pulley and'shaft. Fig. llis a longitudinal section of the same device. Fig. 2 isaview,

partly in cross-section, -of a modification. V

Fig. 13 is-a longitudinal sectionalview showing a modification of thesame. Fig. 14 is a diagrammatic View showing a modification of Vthesheet-stop and gripper mechanism.

Fig. 15 is a diagrammatic View showing a different relative arrangementof the gripper mechanism.

The same part will be found designated byV preferably one suchpin-and-hole connection at each side of the board. By lfting'up the endof` the board the pins are withdrawn from the holes, and the board maythen be slid along on the bars, as toward the cylinder, the pins restingon the bars. This arrangement provides for getting at the inkingapparatus 4without hindrance from the overhead delivery-board.

O indicates the impression-cylinder, which may be driven in any usual orsuitable way. Y

It may oscillate, revolve continuously, or stop, as circumstances mayrequire. The sheets may be fedto the cylinder C in any suitable ordesired manner and are`then delivered thereby upon the `IiXed guides 4and between the sets of tapes 5 6. The tapes 5 are carried by therollers or pulleys 7 8, the rst of which are journaled in the frame ad--jacent the impression-cylinder C and the second of which are journaledinthe fram'eat a distance from the cylinder C. In some cases yit isadvisable to provide that the sheet shall not be lifted Ior blown fromthe tapes 5, and foi-'the purpose of preventing such mishap the'tapes Gare provided. By preference the tapes 6 only bear upon the margins ofthe IOO sheets. The tapes 6 are carried by rollers or pulleys 9 10, thefirst of which are journaled over the pulleys 7 and the second of whichare shown as being journaled in the frame over the pulleys 8. The tapes5 6 are driven in any suitable way. (Not shown.) From the rollers orpulleys 8 1() the sheets are in the specific embodiment of my inventionshown in the drawings, Figs. 1, 3, 4, and 5, run upon the web or ribbon11, of fabric, one end thereof being fast to the cross-bar 12 on thefixed frame of the machine and the other end thereof being fast to ahollow roller 13 on a to-and-fro-movable carriage. This carriage iscomposed of end pieces 14, (but one is showin) which are tied togetherby means of a bar 15, fast at its ends to lugs 16 on the end pieces 14,and a bar 17, fast at its ends to the said end pieces. The end pieces 14are provided with suitable bearings for a shaft 18, on which the roller13 is loosely mounted, so as to turn independently thereof, and withbearings for the ends of a bar or shaft 19, which carries part of thesheet-gripping mechanism, as will presently appeal'. The shaft 19 liesbetween the roller 13 and the bar 15 and is provided with an arm 2Obelow it. The arm 20 is bent, as shown, and is provided with anantifriction-roller 2l and with astud or bearing 22, on which a bar 23is provided. The adjacent end piece 14 is provided with a perforatedlugr 24, through which the har 23 projects. A spring 25 is coiled aroundthe bar 23 between the lug 24 and the enlarged end thereof, which ispivoted upon the stud 22 and acts to press the arm 2O away from the lug24. The arm 2O is stopped when free to move by coming in contact with alug 16 or an adjustable stop 26, passing through the bar 15 and the lug16, or any other adjustable stop may be used. By preference the grippercarried by the bar or shaft 19 is in the form of a continuous bar orplate 27, though this may be replaced by two or more flat bars orgrippers. The gripper 27 is in front of a sheetstop 28, which is securedto the bar 15 and projects above the same. When the bar 19 is free tomovennder the influence of spring 25 and the arm 2O is stopped, asdescribed, the top surface of the gripper 27 is flush with or slightlyabove the top of the stop 28, or it may be held Hush with said top andafterward be raised slightly above the same, all as will hereinaftermore fully appear. By rocking the shaft 19in one direction the gripper27 may be depressed below the top of the stop 28. Above the stop 28 isthe gripper or set of grppers 29. This set of grippers is borne by ashaft 30, which is journaled in arms 3l from the shaftor bar 17. Theshaft 3 0 is provided with an arm 32, to the end of which a rod 33 ispivoted. The other end of rod 33 passes loosely through a lug 34 on theadjacent end piece 14, between the enlarged end of the pivoted endof-the rod 33 and 'the lug 34, and tends to move the shaft 30 one way orthe other, according as the pivot connecting the arm, 32 and the rod 33is above or below the line joining the centers of shaft 30 and the holein lug 34, as will be understood. The shaft 30 is also provided with anarm 36, by which it is moved or rocked when it is desired to open or toclose the grippers 29. This arm 36 has a lug 37 at one side thereof forcoaction with a xed or adjustable abutment 38 on the frame A and with anarm 39, to which an antifriction-roller 40 is attached. The abutment 38acts to close the gripper 29 down upon the top of stop 28, and a lifter41 coacts with the roller 40 to raise the grppers 29 from said stop-top.The lifter 41 is preferably an arm on a shaft 42, which is suitablyjournaled in bearings on or borne by the frame A. The shaft 42 is rockedat suitable times to cause the arm 41 to lift the roller 40 and so causethe shaft 30 to rock until the pivot-connecting arm 32 and rod 33 isabove the line of centers referred to above, Whereupon the springr 35completes the motion of the shaft 30. The shaft 42 is provided with anarm to which a rod 43 is pivoted. `The rod is connected with a suitablecam or other part, (not shown,) by which it is moved at the appropriatetimes to cause the arm 41 to rise, as above described.

The hollow roller 13 may be rotated in any suitable manner, as by meansof the fabric 11 and a tape 44, which may be secured to the roller atone edge of the fabric and to a roller or pulley 45, which is journaledon the framework A and is connected therewith by a spring coiled aboutthe shaft on which the pulley is journaled and having its ends fast tothe frame and to the hpulley, (spring not shown,) as in my pendingapplication for Letters Patent tiled the 19th day of May, 1897, SerialNo. 637,173.

The carriage carrying the roller 13 may be reciprocated by any suitablemechanism, such as shown in several prior applications of mine, and oneof which is partly shown herein. The end pieces 14 are provided withrollers 46, which run on the smooth backs of a pair of racks 47 (but oneis shown) at the sides of the machine. The shaft 18 is provided withpinions 48 at its ends (but one such pinion is shown) which mesh withthe racks 47. The shaft also has a pinion 49 fast thereto at one end,and this pinion 49 meshes with a reciprocating rack-bar 50, which issuitably guided on the frame A. The rack 50 is driven to and fro bymeans of a gear 51 on a shaft 52, journaled in frame A. The shaft 52 isprovided with a second gear 53, which is driven by a reciprocating rack54, working in a guideway 55, bolted t0 the frame A in an obliqueposition, and driven from a crank or cam. (Not shown.)

The operation of the foregoing devices is as follows: The sheets are runout by the tapes 5 o' onto the web 11 and between the grippers 27 and29, which atV this time are in the relative positions shown in Fig. 3and against the stop 28. The sheets may reach the stop 28 at the momentthe carriage is rc- IOO Droar-11 'versing its motion or at any timethereafter prior to the time when the roller 2l runs from under the cam56, and so permits the spring Lotherend thereof.

25 to move the gripper 27 up against the gripper 29, as shown in Fig. 4.After the closing of the grippers the Vsheet `is drawn out over thesupporting-Web 11 -until the carriage reaches the limit of its movementaway from the impression-cylinder C. As the carriage comes to rest orWhile it is at rest the lifter 41 raises the-roller 40 and. rocks shaft30, as described,vto open the grippers y29-that is,

these grippers are lifted from the.r top of the stop 28, and the sheetis now free to pass over the stop and onto the board B during the returnmovement of the carriage. Accordingly as the fabric `ll is now wound upon the roller lthrough the action of the tape 44 the sheet drops, headfirst, onto the boardB and against the end stop 57. reaches the endof'its` return movement the arm-36 or lug 37 is acted upon by theabutment 88, andthe gripper 29 is thrown down against the top of thestop 28, while the grip' per 27'is moved down by the cam 56 in ampletime for the sheetto be run out, as in Fig. 3.

The devices shown in Fig. 5 will now be described. The means for runningout thev be fed by hand to the grippers 58 and bar 15X' a feed-board 59is provided, and the shaft carrying the grippers 58 is placed so thatthe bar 15X is between it and the shaft 18X. theparts having thesuperior X are or may be identical with the like parts hereinbeforedescribed and referred `to without the superior X to their references,and therefore do not need further description.) The carriage for'theslip-sheet-delivering mechanism may be driven independently or it may beconnected at each side to the end piece 14, as by the bars 60 and thescrew-bolts 6l, connecting the bars with the end pieces 14. The

grippers 58 may be opened and closed in any.` suitable way. Thus theymay be connectedl with the grippers 29, as by a rod 62, which isvpivotally connected with arms on the shafts of the said, grippers 29 and58. `The slipsheets are dropped on the board B and against a stop 63 insubstautially'th'e same manner as the sheets from the printing-press. Itwill be observed that the two mechanisms deliver' their sheets inalternation, one beginning at one end of the board B and .the other at'the printing-press vary in length.

As the carriage The feed-board 59 may and their carriage to have theproper position' to drop -the slip-sheets (of nearly the same length ofprinted sheets) upon the printed sheets on the board B. In Fig. 8 thefeedboard 59 is replaced by a feed-cylinderv64, which is journaled inbrackets 65, bolted to the top -of frame A at each side of the machine.The cylinder 64 is provided with grippers 66, which are operated atsuitable intervalsbyanyappropriate means. (Notshown.) The sheets are fedto the cylinder 64 from a feed-board 67 above the same and pointing awayfrom the cylinder C, (the board 59 points toward said cylinder 0,) thussaving space as `compared with the arrangement in Fig. 5.'

rThe slip-sheets are -fedby hand from the board 67 to the grippers ofcylinder 64 and are delivered by the grippers 66 to the grippers 58 andbar 15 at the moment these begin to move toward the cylinder C. Thecylinder 64 is driven by any suitable mechanism (not shown) and takesthe sheets from the board 67 and delivers them to the grippers 58 andbar 15X, the cylinder being so'driven at this time as will secure thatthe slip or other sheets shall be taken byv the reciprocating deliverywithout undue strain being brought upon the sheets. For this purpose acylinder 64'may be caused to move at the same speed as the'reciprocating and delivery mechanism during the time it is deliveringthe sheet thereto. At other times the cylinder 64 may be at rest or moveprogressively, as may be desired. The cylinder 64 andV board 67 may `beadjusted toward and away from the cyllto another set of threaded yholes69 and at'- taching the brackets there to the frame A and' Lalsochanging rods 60 and 63 for others of the proper length.

In the modification illustrated-in Fig. 14 the stop-plate 28 is providedwith notches 70, 0pposite the gripper-s 29-that is, thegrip'pers 29 arenot stopped bythe `stop-plate, but by independent means, as a stop 71 inthefpath of the arm 36. The gripper 27is rfeplacedby a series of fingers27X. lhedotted line indicates the position of a sheet before the grip-In the modification illustratedin Fig. 15 the grippers 29 and 27 are notplaced opposite each other, but the grippers of each set are placedopposite intervals between the grippers of the other'set, and-the partshave motion such that the upper surfaces of the grippers 27 risesomewhat above the plane of the lower Asurfaces of the grippers 29 whenboth sets are in position to `grip sheets,` thus bending the sheet, asindicated by the dotted line in said Fig. 15,',and holding it.

Itis stated abovethatV it is preferred that the tapes 6 shall bear onlyupon the margins IOO IIO

of the sheets. In order to provide for carrying out sheets of variouswidths between the tapes 5 and 6, I arrange to have the pulleys carryingone or more sets of such tapes 5 and 6 adjustable along their shafts.The means forming part of the present invention whereby this adjustmentis readily secured are shown in Figs. 10, 11, 12, and 13. Inasmuch asthe device is applicable to all the shafts and pulleys, I shall in thesefigures give independent reference-numerals to the parts. The shaft 72is provided with a feather or spline 73, and this feather or spline isprovided alongits length with transverse notches 74. The pulley 75 isprovided with a groove 76 to fit over said spline, whereby the pulley isprevented from turning independently of theshaft. The pulley is providedwitha perforation from its rim to its bore, said perforation openinginto the said groove 76. Slidable in said perforation is a pin 77,havingone end shaped to lit the notches 74 and the other end shaped to receivethe end of a coilspring 78, lying behind the said pin in the saidperforation. A screw 79, engaging the threaded end of the perforation,acts as an abutment against which the said spring 78 bears. Whenit isdesired to adjust the tapepulley 75 along the shaft, it is onlynecessary to press with some force upon one side ofthe pulley, and thuscause the pin 77 to move radially outward of the pulley against theforce of the spring and jump over into the next notch 74 as the pulleymoves or is forced along the shaft. In this way the pulleys and theirtapes may be adjusted along the shafts to suit any width of sheet andbear upon the margins or other parts thereof, ras may be desired.

No claim is made herein to the adjustable pulley illustrated in Figs. l0to 13, inclusive, as' that subject-matter forms the basis of anapplication for Letters Patent, a division of this application, filedMarch 26, 1901, Serial No. 52,875.

In the modification shown in Fig. 13 the spline is omitted and the shaft72 is provided with a groove 80, whose bottom is` notched at 74: toreceive the pin 77. The pin 77 in this instance acts as a means ofpreventing the shaft and the pulley from rotating independently of eachother-that is, the pin has a function making it the equivalent of thespline. By preference the notches 711C are Haring, as by being conical,and the pin 77 is shaped to lit them, or the notches 74 may be of thesame width all the way across the spline or groove, and pin 77 may havea wedge-shaped end to lit them, or the notches may have othercross-sections and the pin be shaped to t them. The essential point isthat the shaft and wheel shall have coacting locking members, at leastone of which shall present a concave or convex surface to the other. i
